Rollup merge of #107838 - estebank:terminal_hyperlinks, r=nagisa
Introduce `-Zterminal-urls` to use OSC8 for error codes Terminals supporting the OSC8 Hyperlink Extension can support inline anchors where the text is user defineable but clicking on it opens a browser to a specified URLs, just like `<a href="URL">` does in HTML. https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda
